Question

If 35% of a number added to 39 is the number itself, the number is???

Answer 1

let the number be x
(35% of x)+39=x
35x/100+39=x
(35x/100)+(3900/100)=x
(35x+3900)/100=x
35x+3900=100x
35x-100x=-3900
-65x=-3900
x=(-3900)÷(-65)
x=60

verifying
(35% of x)+39= x
(35/100×60)+39=60
21+39=60
60=60
